<h2>Letters</h2>

<p>Drawing letters to the screen in Processing
uses a technology developed in the mid 1990s
at the Visual Language Workshop at the MIT
Media Laboratory. It is a closed system,
but we have supplied a number of fonts
located in the "font" directory in the main
"processing" directory. We expect to change
the Processing font technology in the future.</p>
